To all whom t may concern:

Be it known that ll, JOHN Boren, a subject of the King of Norway, and aresident of. the city of New York, county of Kings, and State of NewYork, (whose post-otlice address is Flatiron Building, New York city,)have invented anew and useful lmprovement in llncinerators, oi which thefollowing isa specification. The object ot my invention is to provide asimple, economical and durable incinerator which may be operated withgaseous or liquid fuel forithe purpose ot incineratlng garbage vandother material at a minimum expense and without objectionable gases orother resulting products. rllhis object `is accomplished by myinvention, one embodiment of which is hereinafter more particularly setforth `in the accompanylng drawmy improved incinerator;

ings, in which- Figure 1 is a sectional perspective view showing aportion of my improved incinerator with its sheathing omitted; i

Figs. 2 and 3 are sectional views, taken on the lines 2*2 and 3-3respectively, of F ig. 4, looking in the direction of the arrows;

Fig. d is a longitudinal central section of Figs. and 6 are sectionalviews, taken on the lines 5-5 and 6-l6 respectively, of Fig. 4f, lookingin the directionot' the arrows.

Throughout the various views of the drawings, similar referencecharacters desig-y nate similar parts. i

My improved incinerator 1 is provided with a garbage or other refusereceiving chute 2 placed near its upper front and closed by a hingedcover 3, a flue l placed at the upper rear portion of its top, a seriesof burners 5 connected to a main 6, and an ash pit door 7 below theburners 5 and mounted in the conventional manner. The burners 5 are`opposite openings 8 in the iiront 9 of the incinerator so that flamesmay be blown through its front against the garbage in a manner whichwill be described below. rllhe -front 9 is preferably made of cast iron,and in the rear of the same is an asbestos or other heat insulatingsheath which is placed wherever convenient on all sides and the top ofthe incinerator so as to make the device as eilicient as possible.

top have the asbestos sheathing 10 covered by wrought or cast ironprotecting sheets l1, which may be made in any suitable way.,

llt is apparent from Fig. 1 that the greater part of my improvedincinerator is composed of refractory or other similar tire resistingmaterial of some strength and substance with the parts arranged asshown; that is, the top tile 12 has the flue d, as above described, atlits rear, and below its front there is a garbage receiving opening 13placed in the downwardly extending upper tront-tile 14. The 13 areextended so as to cover the front flue, in a manner which will bedescribed below.

`rllhe top 12 is supported at the rear by the vertically disposed slabs15 and 16, the former being the lower, and these slabs are connected bya tongue and groove joint or any other suitable means. rlhe sides 17 and18 are made of a number of slabs in a similar manner and also supportthe top tile 12, and the front 19 is also made with slabs with openings8, as above described, and also an opening 2O for the ash pit oppositethe vdoor An' interior set of tiles 21 and 22 run parallel to the'tiles15 and 16, except where the tile 22'is warped at its upper edge so as toconform to the Hue 4, as shown. These tiles are so placed as to form aflue between them and the outer tiles 15 and 16, and gases walls of theopening can pass into this flue through a recess 23 at so as to permitthe ilames trom-the burners 5 toenter the garbage receiving chamber andalso to permit volatile products from the garbage to reach the flamesand be burnt. The bottom of the garbage receiving chamber is closed by asuitable dumping grate 28 which may be of any suitable form, andnormally lies horizontal.

yIn view ot the foregoing, the operation of my improved incinerator willbe readily un-l derstood. From time to time, the cover is raised andgarbage is deposited in the chute 2 and at once indsits way to thegarbage chamber between the tiles 21 and 22 on the one hand the tile 26on the other and above the grate 28 and below the top tile 12. Here thegarbage is allowed to accumulate until a large enough amount is presentto justify its incineration, which occurs when the burners 5 are lightedin the usual manner so that iames pass from them through the openings 8and slots 27 against the garbage and also over the top of the garbagethrough the recess 26a; and the light products of combustion, throughthe holes 24 and 25. As the garbage is heated, its volatile products mixwith the products of combustion, the heavier passing out through theslots 27 and through the openings in the grate 28 to the ash pit wherethey are drawn up the rear flue to the iiue 4 and the lighter productspass through the plpenings 24 and 25 and thence up the rear When in use,the rear flue soon becomes intensely hot and then becomes a combustionchamber.

When the volatile products have been driven off and nothing remainsexcept the ashes, the ashes may be dumped into the ash pit and allowedto accumulate and finally removed from time to time. If the ash pit getstoo full these ashes may bedeposited in the chute 2, along with moregarbage, and this may be repeated for several times before it isnecessary to remove the ashes.

While I have shown and described one embodiment of my invention, it isobvious that it is not restricted thereto, but is broad In a device ofthe class described, a chami ber having a top, a bottom, a pair of sidevwalls, a front wall and a rear Wall, a pair of vertical partitionsextending from side wall "to side wall within the chamber forming agarbage receiving chamber between them and also forming flues betweenthem. and the front and rear walls respectively, the front wall havingan opening leading to the garbage chamber, the front partition havingits upper end terminating below said garbage receiving opening andhaving its lower end terminating above the bottom of the furnace, agarbage supporting grating extending between the partitions, the frontpartition being provided with a grated portion, the front wall havingopenings directed toward the grated portion in the front partition,burners adapted to force flames through the openings in the front walland through the grated portion of the front partition, the rear artitionhaving a plurality of openings a ove the garbage supporting grate andhaving an opening below said grate leading to the rear fiue and the topof the chamber having an outlet opening leading' from said rear flue.

Signed at the city, county and State of New York, this 29th day ofMarch, 1916.
